16 The waters saw you, God, the waters saw you and writhed; the very depths were convulsed. 17 The clouds poured down water, the heavens resounded with thunder; your arrows flashed back and forth. 18 Your thunder was heard in the whirlwind, your lightning lit up the world; the earth trembled and quaked. 19 Your path led through the sea, your way through the mighty waters, though your footprints were not seen.

Matthew Henry's Commentary on Psalm 77:16-19

Commentary on Psalm 77:11-20

(Read Psalm 77:11-20)

The remembrance of the works of God, will be a powerful remedy against distrust of his promise and goodness; for he is God, and changes not. God's way is in the sanctuary. We are sure that God is holy in all his works. God's ways are like the deep waters, which cannot be fathomed; like the way of a ship, which cannot be tracked. God brought Israel out of Egypt. This was typical of the great redemption to be wrought out in the fulness of time, both by price and power. If we have harboured doubtful thoughts, we should, without delay, turn our minds to meditate on that God, who spared not his own Son, but delivered him up for us all, that with him, he might freely give us all things.
